About

Sang Moo Lee is a pioneering roboticist whose work bridges theoretical control systems and practical industrial applications. His primary research areas include robot dynamics, control architecture, and sensor development for manufacturing environments. Lee’s most influential contribution is his 2002 work on balancing an inverted pendulum using a redundant direct-drive robot, which has earned 16 citations and remains a foundational study in stabilizing underactuated systems. This research demonstrated how robots with extra degrees of freedom can maintain equilibrium under base excitation, a challenge critical for mobile and flexible automation. Lee also advanced industrial robotics with his modularized control architecture for mobile welding robots in shipyards (2008, 9 citations), enabling embedded controllers to coordinate complex welding tasks in harsh, dynamic environments. His work on preshaped trajectory commands for flexible joint manipulators (2002, 3 citations) reduced residual vibrations in high-speed point-to-point motions, improving precision in repetitive manufacturing. Additionally, Lee developed a low-cost dual-axis micro force sensor (2011, 2 citations), making robotic manipulation more accessible for delicate assembly tasks. Through these contributions, Lee has shaped how robots handle instability, vibration, and force sensing, leaving a lasting impact on both academic research and real-world automation.
